IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 119,668, dated October3, 1871.

SAMUEL B. LANE, of Zionsville, of the county of Boone and State ofIndiana, have invented certain Improvements in Grain-Binder Attachmentto Reaping-Machines, of which the following is a specification Ourinvention consists in the construction, arrangement, and operation ofcertain devices to be attached to reaping-machines for automaticallygatheringthe cut grain into gavels and binding them with straw, as willhereinafter more fully appear.

Figure 1 is a front elevation; Fig. 2, a perspective view from the frontleft corner; Fig. 3, a detached view of the twister when opened; Fig. 4,a detached View of the same when closed; and Fig. 5, a perspective viewfrom the rear left corner.

The construction and arrangement of the several parts of which thebinding apparatus is composed will be better understood in describingthem in connection with their operation.

1 1 1 is the frame-work, in which all the binding apparatus is mountedand attached to the reap ing-machine. The grain is raked or carried fromthe grain-table as it is cut, and deposited in the receivers 10 10 bymeans of endless aprons or belts, or other suitable means, operated bythe reaping-machine as it is drawn forward. t is a revolving shaft, towhich are fixed the curved arms 0 O and butt-carrier H, by which thegrain is taken from the receivers 10 in proper quantityto form a gaveland turned over into the ban d-holder E and dropper-arms-ff. The shaft tis rotated by means of the bevel-gears t 25 one of which is on the lowerend of the vertical shaft 5, on the upper end of which is a pinion, t,with which a short segment, 7', on wheel 0' engages once in eachrevolution, the segment 7' and pinion t being so arranged as to give theshaft if one half revolution, leaving the opposite curved arms C so thatwhile those on one side are in position to receive the grain from therake the others are holding and compressing the gavel in the band holderE and dropper-arms f f until the band is brought aroimd the gavel andthe ends twisted together and tucked under theband. On account of theposition of the arms k 70 that bring the ends of the band togetheraround the gavel, it is impracticable to place another arm, 0, tosupport and carry over the butts of the grain, and hence the necessityfor some device for this purpose that will pass under the arms k k asthe shaftt revolves while it projects below to support the butts. Toaccomplish this we pass the bent rod -H, formed as shown, through theshaft t, and connect the ends of it by another rod, H, which also passesthrough the shaft. This rod is pivoted in the shaft at the c ngle sothat the ends may vibrate freely, so that when the shaft is at rest onearm of the rod hangs down in position to catch the butts while the otherarm rests against the shaft so that it can pass freely imder the arm it.But when it has rotated so as to carry the grain over into theband-holder and dropper it drops by its own gravity into the sameposition,thereby not interfering with the rotation of the shaft t, whilesubserving the purpose of aiding to carry over the straw. In order tohold the arms 0 in a proper position, one set of the arms is furnishedat the outer ends with catches G that engage. with a shoulder on aspring, 0 which holds the shaft and arms in the required position untilrotated by the cog-bar r as it engages with the pinion t on verticalshaft t The bandholder and dropper are composed of the curved arms E andff, attached to the shaft d. The arm E, forming a part of the dropper,isalso the band-holder, being a semi-cylindrical shell curved the same asarms ff. The straws for the band are laid longitudinally in theband-holder, at each operation of binding a gavel,- by a person seatedat A, in convenient reach of the straw that is deposited in thegrain-receivers 10 by the endless belts B. When the gavel is depositedin the band-holder and dropper E ff the arms 70 bring the ends of thestraw forming the band together so that the twister L can take hold ofthem. The arms K are formed as shown, and bent at a right-angle at theirouter ends, and are pivoted in the fiame' l 1 1. Rods m connect thesebent portions of the arms 7a with a vertical bar, V said bar having avertical reciprocating movement imparted to it by means of the camgroover on wheel 0' ,formed to give the rod V the proper movement to open andclose the arms m, as required. At the moment the ends of the bands arebrought together the twister takes hold of and twists them. The twisteris composed of jaws L, that are pivoted by their upper ends to the lowerend of a vertical rod, 0, said jaws being opened and closed by thevertical reciprocating movement of the rod, this movement being effectedby means of the cam O on the periphery of wheel 0 and a flange, 0 011the vertical shaft, said cam being shaped so as to time the movement inaccordance with the movement of other parts of the machine. The lowerend of rod 0 is made square and passes through a collar, 0,that is hungto revolve in bar 14. Braces S are pivoted by their upper ends in aflange, a projecting from the bottom of the collar, and by their lowerends to the jaws L. It is by this arrangement that the vertical movementof the rod opens and closes the jaws. The downward movement of the rod0, carrying the jaws L, is simply the result of its own gravity, whichcauses the collar 0 to rest on the face of the cam, the latter beingshaped to give the upward movement at the proper time to close the jawsupon the ends of the band, and to let the jaws descend at the propertime to bring the ends into position to be tucked under the band by thetucker. As soon as the jaws L have clamped the ends of the band a rotarymovement is given to the twister by means of the segment Y that engageswith the pinion 4 just above the flange 0 About the time the twist ismade in the ends of the band a rod, W, is pushed in forward of the band,over which the twisted ends are bent by a forward movement of thetwister, immediately after which the twister descends by its owngravity, so as to turn the ends of the band down over the rod W, and assoon as this is effected the tucker Z moves forward and tucks the endsunder the band, thereby securing them. The backward and forward movementof the twister are effected by means of the two cams on the oppositesides of wheels 0', the shaft 0 bearing against the cam on one side, andthe vertical bar P, to the bottom end of which the horizontal bar 14 isfixed, in which the lower end of the twister-shaft has its bearing,resting against the cam on the other side. In order to release the holdof the twister on the ends of the band, and at the same time to leave itin such position as to hold them until the tucker is withdrawn, we makeone of the jaws L in two parts and attach these parts to the lower endof the shaft 0 by means of springs L, as shown, so that the parts may beopened laterally by means of the wedge 8, attached to the tucker in suchposition that as it moves forward the wedge moves with it and opens thebisected jaw laterally, just after the tucker has shoved the ends underthe band, thus releasing its hold, while the other jaw remainsstationary until the tucker is withdrawn. The tucker is simply a thinbar of iron, pivoted at its forward end to the lower end of lever 7.Said lever having its fulcrum near the upper end in the bracket 9 ismoved back to tuck the ends of a, on the side of wheel 0', this camworking against the projection a. on the lever below the fulcrum, andthe lever 7 is withdrawn and held in position by means of the cam w 011the same side of wheel 0". The rear end of the tucker is supported by arod, 6, that passes through a long longitudinal slot in it, said rodhaving an adjustable nut on its lower end, on which the tucker rests.This end of the tucker has to be raised and held up to admit of thetwister-jaws .opening, and also to allow the arms 70 that bring togetherthe ends of the band around the gavel to work freely below it, and thenlet down into proper position at the proper time to tuck the ends of theband. This we accomplish by means of a cam-groove on the side of wheel0', into which projects the upper end of rod 6, bent at a right angle,and furnished with a friction-roller. The dropping device, consisting ofthe curved arms f and curved band-holder E, attached to the shaft (1,and which also serves to receive and hold the gavel during the operationof binding, is actuated by means of a rack on the lower end of the bentrod 0', that engages with a segmental cog-wheel, A", on shaft 01, saidbent rod being moved up and down by means of a pin furnished with afriction-roll er that projects from it into a cam-groove on the side ofwheel 0''. The gavel-holder and dropping device is made adjustable togavels of various sizes by hav-. ing its forward end journaled in avertical sliding bar, 0?, which is raised and lowered by means of thelever q at the will of the operator seated at A. The rod W, over whichthe ends of the band are turned by the forward movement of the twister,is attached to the bent lever V, and said lever is operated to push inand withdraw the rod by means of a camgroove in the side of wheel 0'',into which a pin furnished with afriction-roller projects from the sideof vertical rod V, the lower end of which is bent into or has a wireattached to it of the form shown that moves in a slot in the other endof the lever. Motion is imparted to the binder by means of a bandconnecting the wheel 0' to any suitable part of the driving mechanism ofthe reaper. This band is made to run loosely, and is tightened to setthe binder in motion by means of a tighteningpulley, M, saidtightening-pulley being hung on one end of a bent rod, t the other endof which is in convenient reach of the operator seated at A. It is bythis means that the quantity of grain carried over to the gavel-holderby the curved arms 0 attached to the revolving shaft t is regulated atwill by the operator.
